产品概述

描述

The STLED316S is a compact LED controller and driver that interface microprocessors to LED displays through a serial 3-wire interface. It drives LED connected in common anode configuration. The STLED316S drives up to 48 discrete LEDs in 8 segment/6 digit configuration while functioning from a supply voltage of 5.0V. Additionally it can be used to drive 8 discrete LEDs which form a part of LED digit. The individual LEDs are wired as segments of a digit and brightness of these individual LEDs can be controlled digitally. The maximum segment current for the display digits is set through a single external resistor. Individual digits may be addressed and updated without rewriting the entire display.
Additionally it includes key scanning for an 8x2 key matrix which automatically scans a matrix of up to 16 switches. STLED316S supports numerictype displays and reduces the overall BOM costs through high integration. Also it provides ESD protection of greater than 4 kV HBM.
The LED controller/driver is ideal as a peripheral device to interface the display with a singlechip microcomputer.
  • 所有功能

    • A single LED digit output (DIG1_LED) can be used to drive up to 8 discrete LEDs
    • Inputs with Schmitt trigger give superior noise immunity
    • 5.0 V (± 10%) for VCC
    • 8-step dimming circuit to control brightness of individual LEDs for LED digit
    • Built-in power on reset and soft-start circuits
    • Drives common-anode LED digits
    • -40 °C to 85 °C operating temperature range
    • Available in SO24 package
    • 8-step dimming circuit to control the overall display brightness
    • 3-wire serial bus interface (CLK, STB, DIN/DOUT)
    • LED driver with 14 outputs (8 segments/6 digits)
    • Output pins connected directly to the LEDs or can be open-drain
    • 40 mA load current capability for each segment
    • Low power consumption in standby mode
    • Single external resistor for output current setting
    • Key-scanning (8 x 2 matrix)
